Submitting a new ticket to any of our sales, support or info email addresses (or through the online interface here) should confirm back to you immediately via email. If you don't receive an email confirmation, then it's pretty likely you won't get our response, either. If this happens, check and make sure your spam filters aren't blocking us. If you suspect we might not be able to email you, it might be a good idea to submit your question on our support forums instead.
